tools for Nextion display on Arduino M2560

Hi all
I am happy because I have long been searching to develop a program that works well. I think I understood the "Chinese?" spirit of the designers of the Human Machine Interface Nextion display
We cannot (as is the case with System 4D) do everything with it.
But to manage a small or large industrial or laboratory project, Nextion is SIMPLE to implement.
I would like to thanks EDC for providing me with a program that was not working! but that allowed me to finalize mine: Waitkey doesn't work well with nextion, we have to use inkey.
You will find here:
-a pps file that shows how to implement the nextion IDE
-the Hmi file
-fonts of characters
-the images used

-two excel files:
1) references
2) the responses returned by the screen in relation to an order

-a Bascom program.prj and its files.bas and.inc : example divided into 4 pages
where we find the main tools. for example to write a text we use the sub nex_txt() etc... built like H.Kipnik (thanks to him)
Each sub, macro or function is explained simply with few program lines.
You don't need video but you can see
https://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewtopic&t=13923&highlight=nextion
it's similar
Now you can debug your program with the help of the instruction "debug on" so simple with Arduino thanks to Mark ! Wink

I'm waiting for your comments

hi JP,

thanks for this. I think all of this is good info to understand how to use the display. it seems all simple Very Happy

but it usually is when someone sorted it out. great to see the progress and cooperation.
So i can conclude that this is the way for at least the low cost standard solution?

You're right, Mark.
for Bascom users who don't want to get ahead of themselves, Nextion is for a reasonable price, the right solution that works.
it's not perfect but it's better and very fast.
and I make myself available to users to help them if necessary.

Hello Kasch
If you look in the blog section you will find https://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewtopic&t=14531
I show my learning how to use the display
Note its not like all the other graphical displays you just need to send the values for the objects you create.
You will also see that it is able to do a lot of the work that the AVR would normally have to do.

Sorry, I forgot to put in pictures yesterday.

I am using the simulator in Nextion Editor
The program for lcd is ok
errors pop up when trying to compile in Bascom.

Program compiles fine here.
Maybe you can share the error code because my glass sphere is broken.

- what kind of error(s) ?
-what is your display ?

From the code displayed it appears your trying to draw circles and boxes on the nextion
there is no need for this on the nextion as you simply use paint or similar program
to make a picture and load it into the nextion.

well,
I checked my program, reinstalled an M2560, a screen NX4832K035 _11
as I had done for the demonstration program
and it all worked out : see the video

check your wiring,your display ?

I did the sub_macro_nextion#2.inc file as H.kipnik did for the ssd1963 display , trying to use the same statment

I found that some screens reacted slower than others.
use "debug on" to understand and fine-tune your application
I use the small Yes-another-Terminal to see the responses.

and please do it step by step, using the remarks '( ') or ' to progress.

-----------------------
Yes Paul You right but Nextion give you the possibility to do , it is a nice tool to draw too.
Now I use "intelligent" they are very very fast !
